if his hair hurts, its probably because its not be kept properly (meaning for his hair type). Treating african-american hair as if its caucausian causes dryness. Just wander down the aisle at walmart, walgreens or wherever where the african american hair products are. The mens hair products are fairly obvious and any might do (moisturizing sheen). Just a little should do. If he is a boy, keeping his hair cut low also cuts down on the curls. If his hair is cut short and his hair still hurts, its not cuz of being african-american. That is very abnormal and i would look into other problems. Namely, I think not having african american role models often causes mixed children to hate the parts that they dont see mirrored and accepted. His voicing that might be cuz of that. Lastly, I would try finding him african american role models (big brothers/big sisters) etc so he doesnt grow up not seeing someone with his characteristics. I think raising a mixed child shouldnt be a second thought, but planned for as it requires some effort to ensure the child grows up secure. Just my thoughts though.
